There's a pervasive tale that the nursery rhyme Jack and Jill is about a thwarted attempt, on the part of King Charles I, to gain extra taxes on beer. The second verse mentions the bruised Jack going to see Old Dame Dob, who patches him up with vinegar and brown paper.
If Jack is indeed Charles, then Old Dame Dob was Elizabeth Carey, aka Dame Robert Carey (pictured later in life).
It's difficult to ascertain the truth of the rumor, but history does tell us that he did return to Elizabeth time and time again. They were close. Like mother and son, even when he was monarch; and that relationship started in 1605.
Prince Charles had barely turned four years old, when he was taken to live with the Carey family, in their new apartment in White Hall Palace, London (modern day Whitehall). It must have been a bitter-sweet period for Elizabeth.
Not only had she got this onerous responsibility, but to sweeten the deal, their eleven year old daughter, Philadelphia, was sent to Coombe Abbey to be raised alongside Princess Elizabeth Stuart. The arrival of the prince, demanding so much attention from Lady Carey, can't have gone down well with one year old Thomas either.
Prince Charles was desperately upset. He'd wanted to stay with Queen Anne; and his new home with the Careys meant that his Scottish nurse - who'd been with him since birth - was sent home to Dunfermline.
He made himself so ill that he was more or less instantly bed-ridden from almost the moment that he arrived. It didn't look good.
Elizabeth Carey devoted a lot of time to him. She gained the little boy's trust and began to work on building up his confidence. Prone to panic attacks, even at four, the priority was psychological care. His family didn't help matters. His brother, Henry, Prince of Wales, seemed to delight in making the boy cry with cruel comments about his prospects and physicality; and his mother seemed convinced that Charles was just being stubborn in his weakness.
Displaying a seemingly infinite supply of patience, Elizabeth helped Charles string together sentences which weren't lost in stammering. It took years to accomplish, but he got there.
Just not fast enough for King James. The boy's father decided that the problem lay in the position of Charles's tongue. He sent a physician to cut beneath it. Elizabeth Carey refused to allow the surgery to take place. She went immediately to see the King and told him outright that it wasn't going to happen.
King James bowed to her judgment and recalled the physician.
Alongside this was the little boy's painful gait. He could hardly stand, let alone walk, at four years old. When he was created Duke of York, at the end of 1605, a courtier had to carry him through the ceremony. James's plan was to fit him with iron boots to build up the strength in his legs and joints.
Elizabeth Carey told him no. James backed off.
Instead, she had some stiff boots made to fit out of Spanish leather. They were hard wearing and helped steady the infant's ankles, but without being too heavy to wear. When Charles was well enough to be out of bed, he had them on his feet.
Elizabeth helped him gradually build up his steps until he could actually walk. It was genuinely painful for him, as the rickets made his bones so fragile.
She'd found another trick too. Charles panicked under criticism, but became anxious to please under praise. She used well delivered encouragement to keep him pushing beyond what all thought were his limitations.
In later years, King Charles I would be deservedly proud of the challenges that he overcame in his infancy and childhood. He gave all credit to both himself and his foster mother. It had been a brave journey for both.
